The following post is from my new article for Knowing Neurons, an online publication about neuroscience and the mind. The Matrix made all of us ask the same disturbing questions: How do I know that the world I see, hear, and touch is real? Can I prove that I’m not actually in a pod created by machines […]Read more "We Are All Brains In Vats"
As long as the nature of consciousness will remain a mystery, we will be in the grip of anxiety. And that is because we are, all of us, haunted by that uniquely human question: what awaits us after death? Although the vast majority of Americans believe in some sort of afterlife, such beliefs are starkly at odds […]Read more "There Is No Ghost In The Brain"
Below is the text of my newest article for the Berkeley Science Review: The brain does many things. It makes decisions, it remembers facts, it moves our muscles, it can do math, and it can communicate with other brains. Each of these abilities are active subjects of neuroscience research. But the brain does something else, which […]Read more "Consciousness Is A Scientific Problem"
I recently had a brief back-and-forth with Bobby Azarian about his new article on Raw Story. Azarian, a neuroscientist at George Mason University, argued that artificial intelligence (AI) could never be conscious. I highly recommend reading Azarian’s article: it’s a great distillation of some key concepts in the philosophy of mind, and he makes an […]Read more "Why Machines Could Be – But Aren’t – Conscious"
The threads that weave the cloth of our mentality are soulless. Our experience of the most beautiful sunset, our most fervent desires, our loftiest thoughts, and our most expansive feelings of love are storms of neural activity, nothing more. Science – and neuroscience in particular – has stripped our mental lives of a soul. But […]Read more "Love In A World Of Atoms"
I recently had the pleasure of talking to Mark Baxter, Ph.D. about the status of neuroscience as a field. Mark is a neuroscientist who studies the molecular mechanisms of learning and memory. This is my second conversation with Mark. Several months ago, we discussed a controversial paper on the effects of marijuana consumption on the […]Read more "Is Neuroscience a Mature Science?"
Cognitive scientists have known for decades that humans are inherently irrational when it comes to making economic decisions. This may seem obvious to a good poker player, who will likely utilize mathematical probability to make economic decisions during a poker game, but to most people the fact that they have systematic economic biases might come as […]Read more "You’re Not As Rational As You Think: Political Philosophy and the Neuroscience of Irrationality"
